This county was created on January 15, 1818, by proclamation of Michigan's territorial governor, Lewis Cass (1782-1866). He named the county in honor of his friend, General Alexander Macomb, who had been born in Detroit when if was still controlled by the British.

We often think of our borders as set in stone, but the reality is that many of our communities have changed shape over the years, and that includes the county itself. When Michigan’s territorial governor, Lewis Cass, created Macomb County by proclamation in 1818, it was enormous and encompassed eight of today’s counties. Over time, other counties formed and broke off, leaving Macomb with the border we have today.

The Township of Orange, one of Macomb’s original townships, was changed to Erin Township in 1843. It has been said this change took place owing to the great number of Irish Catholics settled in the area.

Macomb County celebrates its 200th birthday this year! To honor just some of the many things that make Macomb County what it is today, we’ll celebrate a different theme each month of 2018. In January, we explore the histories of our communities.
